mount/fuse: Fix the place where graph-switch event is logged

2017-01-11T08:39:34+00:00

        Backport of: http://review.gluster.org/16302

fuse-bridge changes the active subvol in fuse_graph_sync(), and not in
fuse_graph_setup(). This patch is written to get more accurate timestamp
in the logs as to when a graph switch actually happened and in the hope
that this will help better in identifying the issue of VM corruption
that users are seeing when they add-bricks.

posix: make sure atime and mtime are set when calling lutimes()

2017-01-09T01:10:59+00:00

When overwriting an existing file with O_TRUNC, the 'atime' was set to
0, meaning the Epoch (01-Jan-1970 UTC). However, the 'mtime' gets
updated correcty.

In case 'atime' or 'mtime' is not passed in the 'struct iatt', the time
values passed to the systemcall are taken from the current values are
returned by lstat().

afr: Ignore event_generation checks post inode refresh for write txns

2017-01-08T11:15:27+00:00

Backport of http://review.gluster.org/#/c/16205/

Before http://review.gluster.org/#/c/16091/, after inode refresh, we
failed read txns in case of EIO or event_generation being zero. For
write transactions, the check was only for EIO. 16091 re-factored the
code to fail both read and write when event_generation=0. This seems to
have caused a regression as explained in the BZ.

This patch restores that behaviour in afr_txn_refresh_done().

glusterd/geo-rep: Fix geo-rep config issue

2017-01-08T11:00:57+00:00

Problem:
Geo-replication config commands fail when geo-rep
status is in 'Created'.

Cause:
During staging phase of geo-rep config, it checks
for the existence of 'monitor.pid' file. But the
pid file gets created only on start of geo-rep.
Hence it fails.

Fix:
Do not check for the existence of pid-file during
staging for config commands. It is not required.

afr: allow I/O when favorite-child-policy is enabled

2017-01-08T10:48:49+00:00

Problem:
Currently, I/O on a split-brained file fails even when the
favorite-child-policy is set until the self-heal is complete.

Fix:
If a valid 'source' is found using the set favorite-child-policy, inspect
and reset the afr pending xattrs on the 'sinks' (inside appropriate locks),
refresh the inode and then proceed with the read or write transaction.

The resetting itself happens in the self-heal code and hence can also
happen in the client side background-heal or by the shd's index-heal in
addition to the txn code path explained above. When it happens in via
heal, we also add checks in undo-pending to not reset the sink xattrs
again.
